Answer:
Relational Database
Step-by-step explanation:
Relational Database (RDB) contains collection of data organized with tables, records (rows) and columns (attributes). In RDB we can create relationships between tables in order to create well defined structure of database.
To query the RDB, it uses SQL (Structural Query Language) in order to perform basic operations on tables such as Create, Read, Update and Delete.
There are four types of relationship that we can defined in RDB, such as One-To-One, One-To-Many, Many-To-Many, Many-To-One.
